a line has a slope of -3, so it's equation has the form y= -3x + b. the line passes through the point (1, -2). what is the y-intercept, b, of the line? ​

Answers

Answer 1

Answer:

y-intercept = 1

Step-by-step explanation:

y = -3x + b

(1 , -2)

Plugin the equation

-2 = -3*1 + b

-2 = -3 + b

-2 + 3 = b

1 = b

y2 = - 4

y1 = - 8

x2 = - 3

x1 = - 2

==========

Equation

m = (y2 - y1) / (x2 - x1)

m = (-4 - - 8) / (-3 - - 2)

m = 4 / - 1

m = - 4

Answer:

(1, -4)

Step-by-step explanation:

(-3, -4) >> (x1, y1)

(-2, -8) >> (x2, y2)

(y2 - y1)           -8 - (-4) = -4

----------- >>>

(x2 - x1)           -2 - (-3) = 1

x always goes first in a coordinate, so

(1, -4)

Parallel lines problem:

Parallel lines have the same slope, so the answer should give a pair of lines whose slope is equal to that of line m, i.e., 2/3.

The only line that fits the bill is line p, whose slops is (8-6)/(12-9) = 2/3; none of the other lines has a slope of 2/3. Thus, b would be the correct answer here for the first image.
